Text in English: Undelete-show-file-confirm ("Are you sure you want to view the deleted revision of the file "$1" from $2 at $3?") has $2 described as "timestamp."
Translation of the previous text to Swahili (individual language):
'revdelete-show-file-confirm' => 'Ni kweli kwamba unataka kulitazama pitio lililofutwa la faili linaloitwa "<nowiki>$1</nowiki>" la tarehe $2 na saa $3?',
